GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 697,235, dated April1902- Application filed December 1, 1900. Serial No. 38.371. (No model.)

To all 1072,0727, it may concern.-

Be it known that I, GoLIN WILLIAM CLAY- BOURNE, of Indianapolis, in thecounty of Marion, and in the State of Indiana, have invented certain newand useful Improvements in Gas-Heaters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which- Figure 1 is aperspective View of a heater.

embodying my invention. Fig. 2 is a side elevation of another embodimentof my invention. Figs. 3, 4., and 5 are respectively per spective'viewsof the lower burner, upper burner, and deflector illustrated in Fig. 2';and Fig. '6 is a detail view, in vertical section, through the upperburner and the deflector, showing the latter supported adj ustably.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention has been to provide a gas-heater for derivingheat from gas, which heater shall have great efficiency; and to suchends my invention consists in the gas-heater hereinafter specified.

In carrying my invention into practice I provide astructure comprising alower burner A, an upper burner B, a deflector O, and suitable gas andair supply pipes. The lower burner consists, preferably, of a number ofhollow radiating arms CL and at, having gasemitting apertures a and a intheir upper surfaces. The number and form of such arms can be varied asdesired, or a circular, annular, or other form of gas-receptacle havinggas emitting apertures can be used. The lower burner is supported in anydesired manner, and such burner has connected with it, preferably at apoint on its under surface, a pipe a for conveying to the interior ofthe burner a mixture of gas and air. Such mixture can be supplied in anydesired manner and from any desired fuel. I prefer to place at the inletof the pipe a a mixer a such as is shown in my Patent No. 652,085,granted May 31, 1900, and to supply gas thereto by a pipe (0*, having acook a therein, the outer end of such pipe being connected to a gasmainC06.

The upper burner B consists, preferably, of a hollow cylindrical castingb, which is preferably closed at both ends and whose lower end fits overand is retained in place by an annular flange a on the lower burner A. Apipe I) is connected with the interior of the casting b at a point wellbelow its top, which pipe is for the purpose of supplying thecombustible mixture for the upperburner. Said pipe is, like the pipe apreferably provided with a mixer b to which gas is supplied through apipe b that is connected with the main a Around the upper portion of thecasting b are provided a series of apertures 19 and I), through whichthecombustible mixture issues from the interior of such casting. At somedistance above the apertures b and b the deflector O is supported in anydesired manner. I have illustrated it as resting upon lugs b and bformed on the top of the casting b. It is obvious, however, thatsupporting lugs or legs could be formed on the deflector or that thelatter could be independently supported from above. The deflector ispreferably a circular body of a diameter preferably as large or largerthan the diameter of the lower burner. Such deflector can be made of anymaterial which will stand a high temperature. The deflector illustratedin Fig. 1 is made of cast-iron in a dish-shape form, there being ribs onits upper side for strength. In Fig. 5 I have illustrated a deflectormade of fire-brick. The deflector can be made vertically adjustable, ifdesired, so as to enable the position to be secured where the bestresults are obtained.

In the operation of my burner a mixture of gas and air is caused to flowthrough the pipe a and into the lower burner, from whence it issuesthrough the apertures in its upper surface and is burned. The heat andthe heated gas ascend and strike the deflector. Similarly a mixture ofgas and air is caused to flow through the pipe I) and into the upperburner, from whose apertures it finds exit. Such mixture is burnedbeneath the deflector, and the latter is preferably at such a heightabove the apertures that the combustion is complete before thecombustible mixture has risen to the lower side of the deflector. Underthe action of the burners the deflector becomes highly heated, and heatis effectively radiated therefrom in all directions. If any of thecombustible mixture is not completely burned before reaching the Theupper burner Bis provided as an aux"- i iliary burner, it being usedalone when a very low fire is required. Either burner can be used tolight. the other.

Changes in the above-described construction can be made which are withinthe scope of my invention. For instance, the two burners and thedeflector can be formed in one casting instead of in separate 1piecesHaving thus described my invention, what I claim is- 1'. In ah'eater,the combination of a burner having gas -e'm ittin'g, apertures, a secondburner consisting of a hollow part located centrally above andsmaller-than the other burneryand having a substantially verticalsurface in which are gas-emitting apertures, and a deflector abovebothofsuch burners; substantially as described.

2. In a heater, the combination with apart having substantiallyhorizontal hollow arms provided with gas-emitting apertures, of a hollowpart located centrally above'saida'rms having a substantially verticalsurface inwhich are gas-emitting apertures, and a defi'ector abovesuchjparts, substantially as and for the'purpose described.

3. In a heater, the combinationwith a pa'rt having substantiallyhorizontal hollow arms provided with gas-emitting apertures, of a hollowpart located centrally above said arms having a substantially verticalsurface in which are gasemitting apertures that are :above the level ofsaid first-mentioned apertures, and a deflector above such parts,substantially as and for the purpose described.

4. In a heater, the combination with a part having hollow arms radiatinghorizontally from a center, such arms having gas-emitting ;-aper.tures,of a hollow part havinga substantially vertical surface in which aregas-emitting apertures, that are above the level of said first-mentionedapertures, such part being located centrally above said arms, and asubstantially circular horizontal deflector above such parts,substantially as and for 'the purpose described. p,

5;. l'na heater, the combination'of aburn er having gas-emittingapertures-and provided with a centrally-disposed flange'on its upperside, thegas-emittingapertures beingoutside of the flange, a secondburner consistingof a hollow cylindrical part havinggas-emittingapertures in iis side and fitted over said flange, and a deflector forboth of said parts supported by said hollow part, substantially asandfor the purpose described.
